I have to say, ever since I got the update my phone has been working beautiful! I have had no band 41 yet, but switching from band 25 to 26 and back has been really smooth. I hardly ever go to 3G now, if I do it switches back to 4G fairly quick. I even found a site that has band 26 working but not band 25. I even tried LTE only to get it and nothing. Must be a good market here.
Update: I did get some band 41 today 6/15/2014.
